The New York Times recently published a piece that asked a pretty darn good question: where have all the organic jeans gone!?

A couple years ago a lot of brands hoped on board the eco-friendly band wagon, but now not so much.

Now companies are looking into sustainable ways to make their denim.

The senior director of the Textile Exchange explains:

"There has been a paradigm shift: it’s about water, toxic waste, scrap on the cutting room floor. Across the board we see companies figuring out how to do the right thing, do it in a way that’s economically viable, move the agenda forward and make a difference."

A good example would be Levi's latest attempt to better the earth with their WaterLess jeans.

Rather than using 42 liters of water to finish the jeans, Levi made it work with 28% to 96% less. The press release says by consuming less water, they're saving 16 million liters of water.

Not bad!

And as we mentioned at the end of 2010, Topshop is also getting eco-friendly with their denim by collaborating with Bionic Yarn.
